Dear Bryan,
I am very pleased that my 'insert' was of such interest/use to you. Timing of such things as occurred comes as no surprise to me, since, from my Mothers' side of the Family strange occurrences in time happen so frequently that I take them for granted these days.
May I ask a favour from Mayhem members please. If someone can supply a drawing or full spec. of Mauretania's siren/whistle, I could get a replica made. For all your ref., MD Whistles (Mike - in the USA), can make any realtime siren/whistle on request. He is a true loco engineer, and very very competent.
Regards, Bernard
